They are not especially close, in general. Weather satellites are often in inclined geosynchronous orbits, to have one of a pair of satellites always over the target area. If the satellite is too low, it will have a very restricted view of the Earth, and will move too quickly to observe long period trends - such as weather fronts.
Air stays close to the Earth due to gravity, which pulls the air molecules towards the surface. Additionally, air pressure increases with proximity to the Earth's surface, which also helps to keep the air close.

How does the moon stay close to earth?
The moon stays close to Earth due to gravity. The gravitational force between Earth and the moon keeps them in orbit around each other. This balance of gravitational forces prevents the moon from drifting away from Earth.
How long can space junk stay in space?
Space junk can remain in Earth's orbit for many years, ranging from decades to hundreds of years, depending on its altitude and the density of the Earth's atmosphere at that level. Some larger pieces may even stay in orbit for thousands of years.
What stop the air going into space?
The Earth's gravity is what prevents the atmosphere from escaping into space. Gravity pulls gases in the atmosphere towards the Earth's surface, keeping the majority of the air close to our planet. Additionally, effects like the Earth's magnetic field also play a role in protecting the atmosphere from solar wind erosion.
How do hot air balloons stay in air?
hot air rises
When clouds form close to the ground they are called?
When clouds form close to the ground, they are called fog. Fog is essentially a type of cloud that forms near the Earth's surface when the air temperature cools and reaches saturation point.
Why is the air so close to the surface of the earth?
The air is close to the surface of the earth because gravity holds it there
What gas makes up close to one quarter of the air surrounding earth?
Oxygen makes up close to one quarter of the air surrounding Earth.
What makes up close to one fourth of the air surrounding the earth?
Oxygen makes up close to one fourth of the air surrounding the Earth.
Why is the air close to the Earth's surface dense?

What do dolphin live?
Dolphins live in the earth's warm ocean water. They have to stay somewhat close to the surface to be able to come up for air every 20 to 30 minutes.
Why do the gases in the earth atmosphere stay close to the surface of the planet?
Gases in the Earth's atmosphere stay close to the surface due to the force of gravity acting on them. Gravity pulls the gases towards the center of the planet, keeping them from escaping into space. The mass of the Earth is sufficient to maintain an atmosphere that surrounds the planet.
Why is the air close to the earth's surface very dense?

When bees stay close to the hive rain is near by?
Bees stay close to the hive when rain is nearby because they can detect changes in air pressure. If is going to rain and the air pressure drops, the bees will remain in their hives.
How long can life go on?
well as long as earth can stay near but not to close to the sun
How does the sky affect the earth?
The sky is air and gravity keeps the air close to the ground so we can breeth it in .
Does Mercury have clean air?
Mercury does not have any air. It is too close to the sun to have the kind of atmosphere that we have on Earth.
How does air pressure drop?
Air pressure close to surface of the earth is 1 atmosphere. But as the altitude increases, air gets thinner in other words the molecules in air are farther than the one close to earth's surface. This causes the atmospheric pressure to decrease as we increase in altitude.
